dpx folder name when converting MKV --> DPX

[dlasusa]

Hi all,

I've notice when converting an MKV file (encoded with RawCooked) to DPX files (also using RawCooked). If I point the output for example to C:\temp RawCooked will put the dpx files in a subfolder (based on what looks like the folder the original dpx files were in).
I assume this is stored in the reversibility data attachment in the mkv?

If so, is there a way to parse the stream?

I found with ffmpeg I can create a file which I think contains the data...

ffmpeg.exe -dump_attachment:t:0 out.txt -i .\test2.mkv

I can open the file in hex editor, but it's not very easy parse.

All I'm really after is the name of the folder RawCooked plans to create, so if there is another/better way to access that info, it would be super helpful! Or...is there a way to pull that out of the reversibility attachment?

Thanks!

If so, is there a way to parse the stream?

MediaInfo trace feature (" --Details") is able to show the content of the RAWcooked reversibility file, either the MKV file or the extracted attachment, see below.
We need to show this information in rawcooked --info, will do.

Would an option for removing the top folder during extraction be useful? If so, please fill another issue (I reserve this one for rawcooked --info).

Hi @JeromeMartinez Thanks so much for the reply. Perhaps I'm calling MediaInfo incorrectly, but when I try to use the --details option on an .mkv file (created by rawcooked), it simply opens a blank MediaInfo gui window. Attaching a screenshot of what I tried to make sure I'm not missing something super simple and that I'm using the option correctly?

I do think showing the information via rawcooked --info would be a useful feature so it's available via a single tool.

For my current purposes, as long as I can identify the folder, I personally don't need an option for removing the top folder during extraction. That said, I think it could be a useful addition to have better (more expected) control of where the files are going when running rawcooked in a programmatic fashion. I'll open an issue like you suggested for easier tracking.

Thanks!!

MediaInfo gui window

You are trying with the GUI version, please download and use the CLI (command line interface) version for the option.
With the GUI, menu debug, "details - 10" line, and open a file.

[dlasusa]

ah! Works perfectly now! Thank you!! I'm going to leave this open for the rawcooked --info enhancement.
